Collaborative Asteroid Photometry for 3653 Klimishin, 4748 Tokiwagozen and 9951 Tyrannosaurus

Photometric observations of three main-belt asteroids were made in order to acquire lightcurves. The synodic period and light curve amplitude were found for: 3653 Klimishin 6.783 ± 0.001 h, 0.21 mag; 4748 Tokiwagozen 39.78 ± 0.01 h, 0.42 mag.; 9951 Tyrannosaurus 3.767 ± 0.004 h, 0.21 mag. Asteroid 4748's lightcurve shows a few interesting features which suggest the opportunity of further observations in order to verify a possible "tumbling" nature.
